[0028] Production of Coenzyme Q by Fermentation-Extraction Coupled Method 10

[0029] Direct extraction of coenzyme Q produced by microbial fermentation by fermentation-extraction coupling method 10 There are two main problems to be solved: 1. Coenzyme Q 10 It is an intracellular product obtained by microbial fermentation, so it is necessary to choose a good cell permeabilizer to dissolve it from the cell, creating a prerequisite for the coupling extraction of fermentation extraction; 2. To select a suitable organic solvent to extract extracellular coenzyme Q 10 , to determine the optimal amount, optimal time and optimal extraction time of its addition, and the addition of this solvent has a significant effect on the growth of bacteria and coenzyme Q 10 output is not affected.

Abstract

The invention provides a method for making coenzyme Q10 by means of sphingosine monad fermentation, extraction and coupling. The method comprises the following steps that: sphingosine monad strain is inoculated in liquid medium suitable for sphingosine strain; soybean oil with the volume occupying 1 to 5 percent of that of the liquid medium is added in the liquid medium so as to carry out cultivation at a temperature of between 25 and 28 DEG C for 24 to 36 hours; then, normal hexane with the volume occupying 20 to 50 percent of that of the liquid medium is added in the liquid medium so as to carry out cultivation at a temperature of between 25 and 28 DEG C for 6 to 12 hours; after the reaction is completed, the reaction liquid undergoes delamination and then the organic layer is taken out so as to obtain the coenzyme Q10 after separation and purification. The method has the advantages of high recovery rate of extraction solvent, economization on manpower and material resources, simple and time-saving method and high yield of coenzyme Q10, and is propitious to industrialized production.
